The following quickstart is for Windows, the Mac & Linux page is here.

UE9 Quickstart for Windows

This section demonstrates, step by step, how to perform two common operations in the free LJControlPanel application.

1. Install the Labjack driver and application suite.
The utility application referenced in the following steps (LJControlPanel) is only available in the Windows Installer. The package for Linux and Mac will allow communication to the UE9, but no similar application is available for Mac and Linux at this time.

U6/U3/UE9 Devices

U6 U3 UE9

Windows details
Windows Installer 48.56 MB 2013-06-04 15:58

This is the installation package for Windows for the U3, U6, UE9, T7 and Digit. It supports both 32-bit and 64-bit versions of Windows XP, Windows Vista, Windows 7 and Windows 8. All high-level functions within the UD and LJM libraries will be available through this installation. Example code using these libraries can be downloaded according to language in the programming section.

This installation includes the driver, libraries, documentation, and utility applications listed below

Utility Applications
  • LJControlPanel 2.31 - Simple configuration and testing utility for the U3/U6/UE9
  • LJSelfUpgrade 1.29 - Updates firmware on the U3/U6/UE9
  • LJLogUD 1.12 - Logging program up to 10 Hz for the U3/U6/UE9
  • LJStreamUD 1.14 - Logging program up to 80,000 Hz for the U3/U6/UE9
  • Kipling 1.0.0 - Basic configuration and testing application for the T7
  • Otero 1.24 - Configuration and downloader for the Digit series loggers
Code Libraries
  • LJM Library 2.42 - Library of high-level code functions for the T7/Digit
  • LJM Constants 2013.5.30 - JSON constants file for the LJM library
  • UD Library 3.35 - Library of high-level code functions for the U3/U6/UE9
Low-level Driver
  • LabJackWinUSB Driver X.XX - Driver for Windows USB communication to and from all LabJack devices

Tip: Uninstall previous versions before installing new versions. If a LabJack is connected during installation, unconnect and reconnect when done.

The normal ways of uninstalling previous versions of the package are:

  1. Do Start => Programs => LabJack => Uninstall.
  2. Go to Windows Control Panel (not LJControlPanel), then go to Add/Remove Programs, then find "LabJack" or "LabJackUD".

Here are the alternative manual steps:

  • Go to Start => Programs, find the LabJack group, right-click on it, and delete from the start menu.
  • On your hard drive delete the LabJack folder which is usually in "C:\Program Files\" or "C:\Program Files (x86)\"
  • Find and delete delete labjackud.dll in your system directory (i.e. "C:\windows\system32\" or "C:\windows\SysWOW64\").

Mac OS details
Macintosh Package 188.37 KB 2013-05-01 14:31

This is the installation package for Mac for the U3, U6, UE9. It is a native USB driver, so only low-level functions can be used. Low-level functions are documented per device in the low-level section of their datasheet. This installation does not include any utility applications.

Low-level Driver
  • Exodriver X.XX - Driver for Mac and Linux USB communication to and from all LabJack devices

Installation guide with demonstration code here.


Linux details
Linux Package 126.83 KB 2013-06-12 23:54

This is the installation package for Linux(same as Mac) for the U3, U6, UE9. It is a native USB driver, so only low-level functions can be used. Low-level functions are documented per device in the low-level section of their datasheet. This installation does not include any utility applications.

Low-level Driver
  • Exodriver X.XX - Driver for Mac and Linux USB communication to and from all LabJack devices

2. Connect the UE9 to the computer or hub.
The status LED should blink at power up and then stay solid on. If Windows asks about installing new hardware accept the defaults.
3. Run LJControlPanel.
LJControlPanel is a free application installed along with the driver. You should be able to find it in the Start Menu links.
4. Click "Find Device".
5. Select the connection (i.e. "USB - 1").
The right hand side of the screen will change.
6. Click "Test".
This brings up the test panel where you can read all inputs and write all outputs. This test panel is a great tool to use often and lets you check out basic hardware operation before trying more complex software.
7. Connect jumper wire from DAC0 to AIN0.
DAC stands for "Digital to Analog Converter", AIN stands for "Analog Input", FIO stands for "Flexible I/O"
8. Control Panel will read the voltage level of FIO0 at DAC0.
This shows the standard way to read voltages.
9. Connect one end of the jumper wire to GND, touching the other end to FIO0.
GND stands for Ground. Try connecting and unconnecting the FIO4 end of the jumper wire.
10. Control Panel will read the digital input as changing.
The FIO4 checkbox will change from selected to unselected showing that there is a voltage change.
For complete information on the capabilities of the UE9, refer to the UE9 User's Guide.

Is it possible to read voltages higher than +5V on any of these? Is it possible to output higher voltages or sinusoids?

You need to use a voltage divider or the LJTick-Divider.  See Section 2.7.3.6 of the UE9 User's Guide.

You need to externally amplify the DAC outputs or use LJTick-DACs for +/-10 volt outputs.  See Section 2.8.1.2 of the UE9 User's Guide.

For waveforms, such as sinusoids, you need to send updates 1 at a time to create the desired waveform.  See the related app note.  The app note also mentions Stream-DAC available on the UE9.

Is it possible to read both positive and negative voltages in a single channel using the analog inputs on the LabJack UE9?

If you are asking about differential measurements, no the UE9 does not support differential.

Yes, the UE9's inputs can be set to bipolar mode which will read ±5V.
